John Travolta busted out his iconic “Saturday Night Fever” moves at Madonna’s annual Oscar party. Spies said that when “Stayin’ Alive” by the Bee Gees came on at the bash at Guy Oseary’s LA home, Travolta did the moves from the 1977 classic for which he was nominated for an Oscar, to guests’ delight. Everyone “followed and started dancing,” we’re told. Madge’s guests included Ashton Kutcher, Selena Gomez and Daniel Day-Lewis. (There was no word on whether DDL joined in, though we’d like to think he did.)
